I install QGIS 2.8 in debian (linux) through nightly jessie (qgis testing) and I see that SAGA is not in processing toolbox, so I install saga gis software but still it doesn't appear in processing.
...

When processing 30m and 10m DEM data downloaded through the National Map Viewer from the National Elevation Dataset, we noticed horizontal and vertical striping not only in the produced results, but ...

I want to show soil transmissivity per pixel. Thus, I determine water holding capacity of each pixel (ignored other effective parameters). Respectively, I wonder, What is the soil data format and How ...

I create channel network and catchment area from a DEM with SAGA GIS. I know that flow is starting from a cell to an other cell. Firstly, a cell is filled with water and then it is starting to flow ...

I am a new user of SAGA GIS software.
I need to interface the Civil 3D 2015 and Hec Ras software in order to create a flooding map.
In order to put in communication the two softwares, I have to use ...

I am trying to follow along with this exercise using my own DEM.
I have done the first step, creating the catchment area, with no trouble. When I try to run the Channel network algorithm, however, I ...

I want to create a flood map using Quantum GIS. First of all I create catchment area (flow accumulation). Then, I delineate a Channel Network by applying a threshold to flow accumulation. So I want to ...

I downloaded QGIS 2.6.1-2 (Brighton) yesterday from OSGeo4W-setup-x86.exe using the advanced installation option on a machine running on windows 7 professional. The download worked Ok except for saga ...

I'm using QGIS 2.6 Brighton on Windows with SAGA 2.0.8 installed using OSGeo4W. I have the same versions installed on OSX as well which is not having this problem.
On Windows, I'm trying to extract ...

I have a vector dataset of mean annual precipitation polylines, and I would like to generate a raster from them. I'm not sure the best way to go about it.
ArcGIS has the Polyline to Raster tool but ...

I am using Ubuntu 12.04 and want to do image classification in SAGA. SAGA has numerous classification algorithms which is not present in GRASS and QGIS. I am new to SAGA, but more accustomed to work ...

I tryed to calculate the LS Factor at SAGA, using a slope raster and the area raster, both at the same EPSG, and the error:Unable to execute the algorithm
the error means something with the coordinate ...

I tried to get a grid by interpolating LAS file using Ordinary Kriging. But the product grid has many pixels which values strongly stands out from average surface - I mean one pixel sinks nad spikes. ...

Right now, it is just a Blackbox-way to interpolate a DEM. I know to some extent how for example the nearest-neighbour-method works, but I have no idea about b-spline. It would help to understand the ...

Recently i decided to start working in Ubuntu (version 14.04). My first step was to add the ubuntugis-unestable repository, and then proceed to install SAGA, GRASS, OTB, QGIS and the bindings between ...

frequently I am using (R)SAGA, but after SAGA became >2.1.0 the R package is no longer working. The last update for RSAGA was 07/2013.
Thus I downgraded SAGA to 2.1.0 (first try was skipping the ppa ...

I digitized contour lines from topographic maps and created a DEM. With the DEM, I estimated the boundary of a catchment area. Estimated positional accuracy of topographic maps is RMSE = 65 m, with a ...

I am relatively new to the SAGA software, I have only used it for small amouns of data, and for basic calculations.
My data is obtained by mapping certain areas in GoogleEarth, then, overlaying the ...

I need to test segmentation of a 12000 x 12000 pixels scene.
I successfully compiled OTB in Ubuntu 14.04 and ran the process.
But when I tried to start SAGA, I got a startup error.
I found that gdal ...

I'm using windows 7 on 64 bit and using Qgis 2.6.0.I'm trying to process some Tifs from the console using the processing toolbox and saga:slopeaspectcurvature. This is pretty much how my code looks ...

I am not familiar about Lidar. I want to measure trees height and number of trees.
I guess, watershed = to locate the trees, local maxima = to measure trees height. I used these methods in SAGA GIS.
...

Are there any tools or existing workflow which convert raster features (such as roads, rivers, electric lines etc.) which are (or can be) multiple cells wide to a single cell widht (i.e, center line). ...

I want to calculate the RMSE of two grids based on their z-value: a calculated and a reference grid.
I do have the statistics: Cells, Range, Min, Max, Sum, Mean, Variance, St.dev.
How could I solve ...

how can I calculate sums, averages etc of raster-points (multi-band) per polygon of a vector-layer. I was told that this is called "zonal statistics". I tried that with QGIS first.
There is a way to ...

The ability to write and run cross platform scripts for QGIS using python is OUTSTANDING! However, when I try to run the SAGA:MERGESHAPESLAYERS algorithm from a python script it works fine in windows ...

I am trying to reclassify a raster using the Saga Reclassify grid values tool in the QGIS Processing Toolbox, but am getting an unexpected entirely black raster. I have verified my original points and ...

I am trying to locate areas upstream and downstream of a point of interest in QGIS in order to determine possible areas of origin upstream and areas of impact downstream. I have used a DEM to create ...

I have a points shapefile and I want to create a rectangular buffer (22 x 16 km) around each point. My goal is to create a 16x22 km grid where each of the points is the centroid of the grid. Seed the ...
